Nine: Sudoku

Variant sudoku, flick to play

$4.99

Sudoku on your iPhone, iPad, Mac, TV and wrist. Classic, Thermo and Killer, every puzzle proof-checked, every hint explained. Solve together on SharePlay. Nine is sudoku built for wherever you are...on the couch, the train, the desk, or the wrist. One purchase for iPhone, iPad, Mac, Apple TV and Apple Watch, and your boards follow you between them. FLICK TO PLAY Tap a cell and a ring of nine digits blooms around it. Flick toward the one you want. On the Mac it's the arrow keys and the number keys; on Apple Watch it's the Digital Crown; on Apple TV it's a swipe and a tap on the Siri Remote, or a game controller. PUZZLES YOU CAN TRUST Every board has exactly one solution and is checked by a logic solver before you see it, so you never need to guess. Three difficulty bands set which techniques a puzzle may ask for... from a relaxed first coffee to a proper fight. CLASSIC, THERMO AND KILLER Turn the page from classic sudoku to Thermo, where digits climb along each thermometer, and Killer, where cages add up to their sums. A COACH THAT EXPLAINS Stuck? Ask why a cell must be a seven and Nine walks you through the reasoning instead of just filling it in. The Technique School teaches each method on boards built to show it. SOLVE IT TOGETHER Start a board on a FaceTime call and everyone gets the same puzzle through SharePlay. A soft dot shows how far each friend has got, and nobody sees a time until everyone has finished. YOUR SOLVE, REPLAYED Finish a board and watch it play back as a comet across the grid, with a debrief of where you flew and where you slowed down. Your history keeps every solve. MADE FOR EVERY SCREEN • iPhone and iPad: touch-first, with Apple Pencil handwriting and a drafting table on iPad. • iPhone Duo: open it and the board becomes a book spread, the crease falling on the board's own box rule, with the controls on one page and the digits on the other. • Mac: keyboard-native, with a menu bar, a History window and a compact always-on-top desk mode. • Apple Watch: zoom into one box at a time and dial digits with the Crown. • Apple TV: a full-screen board across the room, with settings beside it rather than on top of it, played on the Siri Remote or a game controller. • Home Screen widget with a board you can play. MAKE IT YOURS Ten accent colors, dark-first, with light mode on iPhone, iPad and Mac. QUIET BY DESIGN No ads. No in-app purchases. No account. No tracking. Nothing blinks at you while you think. Game Center leaderboards and achievements, iCloud sync across your devices, and full support for VoiceOver and Dynamic Type. Available in English, German, Spanish, French, Italian, Japanese, Korean, Dutch, Brazilian Portuguese and Simplified Chinese.
